The limits are determined either in beats per minute (bpm), as a percentage (%) of your maximum heart rate, or as a heart rate reserve (% HRR).

The Polar FT2 Heart Rate Monitor also uses Maximal oxygen uptake (VO2max) and Manual target zone. Heart rate is the measurement of the work your heart does. Heart rate can be expressed as the number of beats per minute or as percentage of your maximum heart rate.

Heart rate can also be expressed as a percentage of your heart rate reserve, meaning the difference between your resting heart rate and maximum heart rate (HRR = HRmax - HRrest). In Polar software or during strength training, heart rate can be displayed as a graphical trend. You can define your target zones for a training session based on heart rate to help define the right intensity.

When you are out of the preset zones, the Polar FT2 Heart Rate Monitor will give a visual and audible alarm. This feature enables you to define the target zone as you want and is suitable for your training.

You can set the target zone for your training as beats per minute (bpm), as a percentage of your maximum heart rate, or as a percentage of your heart rate reserve (HRR%). Coded heart rate transmission automatically locks in a code to transmit your heart rate to the training computer.
